This software enables designs of spiral cylindrical torsion springs with variations in geometry and strength under static or cyclic loads. It caters to both the Imperial and Metric units, supports ANSI, ISO, DIN standards, and is compatible with several 2D and 3D CAD systems.

The application is developed in MS Excel, and is multi-language, supporting both Imperial and Metric units. It is also feature-rich, with several main tasks that it can help users solve. These tasks include automatic design of the spring, selection of the optimal design of the spring with respect to strength, geometry, and weight, and static and dynamic strength tests.
Users will also find support for cold formed springs and hot formed springs. Additionally, the software can calculate the working forces of a spring with known production and mounting dimensions, and the mounting dimensions for known spring loading and production parameters.
To help in the design process, the software includes a table of commonly used spring materials according to ISO, ASTM/SAE, DIN, BS, JIS, and others. It also supports 2D and 3D CAD, compatible with software such as AutoCAD, IntelliCAD, Ashlar Graphite, and SolidWorks.
The calculation process is based on data, procedures, and algorithms from specialized literature, as well as the standards EN 13906-2 and DIN 2088. This module is a part of the larger MITCalc - Mechanical and Technical Calculation Package, which includes calculations for gear, belt and chain drives, springs, beam, shaft, bolt connection, shaft connection, tolerances, and many others.
Overall, this software is a comprehensive and reliable tool for anyone involved in the design of spiral cylindrical torsion springs made of wires and rods in circular sections. Its many features and ease of use make it a valuable addition to the toolkit of engineers and designers alike.
